Erdungsmatten: Können sie Ihr Wohlbefinden steigern?

What is a grounding mat?

A grounding mat is a flat, electronic, plug-in device designed to imitate the effects of walking barefoot on the earth's surface. They are usually made with conductive material, often infused with carbon.

Dr Pamela Tambini, a double-board certified physician in Internal Medicine and Addiction Medicine says a grounding mat simulates the benefits of connecting directly to the Earth.

She explains that the concept of 'earthing' or 'grounding' is based on the idea that the Earth carries a natural electric charge. When you make physical contact with the ground, your body can absorb electrons that help balance your electrical charge. A grounding mat enables you to experience these potential benefits indoors by using conductive materials that connect either to a grounded outlet or directly to the Earth.

"Grounding mats allow electrons to flow from the earth into your body," says the Medical Director of Engage Wellness, Massachusetts, USA. "When your bare skin touches the mat, it’s thought to help neutralise free radicals in your system, potentially reducing oxidative stress and inflammation."

Improved sleep

Grounding mats may help regulate your body's stress hormone (cortisol). When your cortisol is well-balanced, you tend to enjoy more restful sleep.

Tambini says: "Balanced cortisol levels can support your natural sleep-wake cycle. This usually leads to better quality sleep."

She adds that people who regularly use grounding mats often report falling asleep quicker and waking up feeling more refreshed.

Reduced stress and anxiety

Lower cortisol levels are often linked to an increased sense of tranquillity.

Seth Bolton, addiction recovery specialist and member of the National Counselling and Psychotherapy Society (MNCPS) says this may help you feel less stressed and anxious.

Tambini agrees that grounding mats promote relaxation by activating the parasympathetic nervous system, which calms the body.

"This shift can help reduce stress and anxiety levels," she adds. "Many users describe feeling more relaxed and centred after grounding sessions."

Reduced inflammation

Because grounding mats are thought to neutralise free radicals - unstable molecules that can harm your cells - they might also help lower inflammation.

Tambini explains that inflammation is at the root of many long-term health conditions, and is a common underlying cause of persistent pain.

"By neutralising free radicals, grounding may decrease swelling and oxidative stress," she says. "This reduction in inflammation may benefit people with arthritis, autoimmune conditions, or exercise-related soreness."

Reduced blood viscosity

Grounding may contribute to a slight decrease in the thickness of your blood, which allows it to flow more efficiently.

Tambini says that lower blood viscosity can improve your heart health. If your blood flows more freely, this reduces strain on the cardiovascular system, lowers your chance of developing blood clots and improves your overall circulation.

"Improved circulation allows oxygen and nutrients to reach your body's tissues more effectively," she adds. "This could support heart health, and enhance overall vitality."

Faster wound healing

More research is needed to determine whether grounding mats can help your wounds heal faster.

However, Tambini says that if they can reduce inflammation and improve circulation, they may be able to accelerate wound healing.

"These factors may create an environment in the body that supports quicker recovery," she explains.

Who might benefit from a grounding mat?

If you're dealing with health issues such as long-term pain, inflammation, stress, anxiety, or sleep difficulties, it's always best to talk to your doctor about the most appropriate course of action.

Tambini says that while grounding mats may offer some a simple, relatively safe way to find relief from their symptoms, they are not a substitute for conventional treatments.

"Many people report positive experiences, so as part of a well-rounded wellness plan, they can complement other healthy habits," she says. "However, consulting a healthcare professional with your specific health concerns is always best."

There's no solid scientific evidence to say that grounding mats can definitively treat certain health conditions. However, if using one helps you sleep better and feel more relaxed, that alone can have positive effects on your wellbeing. If it works for you, by all means continue.
